Abstract

A method and system for selecting fold lines on a sheet to be inserted into a windowed envelope includes scanning the windowed envelope with a scanner to determine the location of the window on the envelope. The location of a data block on an insert to be inserted into the windowed envelope is also determined. The position of one or more of the fold lines on the sheet to be inserted is determined such that a data block printed in the determined location on the sheet will appear behind the envelope window when the sheet is folded in accordance with the determined fold line pattern and inserted into the windowed envelope. The efficiency and flexibility of the system can be enhanced by providing an operator with possible standard and nonstandard fold patterns that will enable proper insertion of the folded sheet into the envelope. In such case, when the sheet is folded with the selected fold pattern and inserted into the envelope, the required data block information will appear behind the appropriate envelope window. The paper handling equipment adjustments for the selected fold type and proper loading of the insert materials into the insert feeders can be communicated to the operator or used to automatically adjust the folding mechanism for the selected fold pattern. Additionally template information can be generated by the system to provide the operator with information on the proper location for the address block information on the sheet in order to position the address information behind the window in the envelope for a selected standard fold type.

Claims

1. A method for folding a sheet for insertion into an envelope having a window, comprising the steps of:

capturing an image of the envelope to determine a location of a window on said envelope;

determining a location of a data block on a sheet to be inserted into said envelope;

determining the position of one or more fold lines on said sheet such that said data block will appear behind the window of said envelope; and

folding said sheet in accordance with said one or more determined fold lines.

2. The method as defined in claim 1 wherein said data block is preprinted on said sheet and the step of determining said location of said data block is by scanning said sheet with a scanner to define an image of said data block.

3. The method as defined in claim 2 wherein said step of determining said location of said data block further includes the step of displaying an image of said data block on a touch screen display and selecting displayed points associated with the location of the displayed data block.

4. The method as defined in claim 1 wherein the step of determining the location of said window further includes determining the external dimensions of said window.

5. The method as defined in claim 1 wherein the determined position of one or more fold lines is selected from a plurality of sheet fold patterns.

6. The method as defined in claim 5 further including the step of communicating said plurality of sheet fold patterns to a user on a display which displays said plurality of sheet fold patterns.

7. The method as defined in claim 1 wherein said step of capturing an image of said envelope includes the steps of:

placing a contrast card into the envelope such that the contrast card is viewable through the window,

scanning the envelope to obtain a high contrast image thereof, and

calculating the location of the window from the high contrast image.

8. A method for folding a sheet to be inserted into a windowed envelope, comprising the steps of:

determining the external dimensions of said windowed envelope;

capturing an image of the windowed envelope to determine the location and dimensions of a window on said windowed envelope;

determining the location and dimensions of a text block on said sheet to be inserted into said windowed envelope;

determining a fold line pattern on said sheet Such that a text block printed in said location on said sheet will appear behind the window when said sheet is folded in accordance with said determined fold line pattern and inserted into said windowed envelope; and

,

folding said sheet in accordance with said determined fold line pattern.

9. The method as defined in claim 8 further including the step of automatically adjusting a folding mechanism to fold said sheet in accordance with said determined fold line pattern.

10. The method as defined in claim 8 further including the step of communicating to a user setting adjustments for a folding mechanism to fold said sheet in accordance with the determined fold line pattern when adjusted to said communicated setting adjustments.

11. The method as defined in claim 8 further including the step of communicating to a user the orientation of said sheet to be inserted into said folding mechanism and the setting adjustments for said folding mechanism to fold said sheet along said determined fold line pattern.

12. The method as defined in claim 8 further including the step of scanning the sheet to capture a scanned image of the text block and wherein said step of determining said location and dimensions of said text block further includes the step of displaying the image of said scanned text block on a touch screen display and selecting displayed points associated with the location of the displayed text block.

13. The method as defined in claim 8 wherein said step of capturing an image of said envelope includes the steps of:

placing a contrast card into the envelope such that the contrast card is viewable through the window,

scanning the envelope to obtain a high contrast image thereof, and

calculating the location of the window from the high contrast image.
